Question

If point P lies on the line y = -1, find the following
a) Its Y-coordinate
b) Its X-coordinate

• A. x = -1, y = 2
• B. x = -1, y = -2
• C. y = 1, x = -1
• D. y = -1, x can be any real number.

Answer 1

The correct option is D y = -1, x can be any real number.

Since it is given that the point P lies on the line y = -1, its y coordinate will be -1.

Its x coordinate, however, can be any real number.
